RFC Editor Note:

Section 5. "Security Considerations"

OLD:

   This document specifies the contents of GMPLS TE TLVs in ISIS.  As
   these TLVs are not used for SPF computation or normal routing, the
   extensions specified here have no direct effect on IP routing.
   Tampering with GMPLS TE TLVs may have an effect on the underlying
   transport (optical and/or SONET-SDH) network.  Mechanisms to secure
   ISIS Link State PDUs and/or the TE TLVs can be used to secure the
   GMPLS TE TLVs as well.
